All of the numbers refer to measurements in millimeters.The first number is the width of a lens. The second is the distance between lenses (width of the nose bridge). And the third is the length of a temple (one of the arms).A rule of thumb is that spy sunglasses should be as wide as your face. You can measure your face by holding pencils on each side at eye level and bow down on a piece of paper. To know the width of the glasses, multiply the lens width by two (one for each lens) and then add the distance between lens. Then add around six millimeters extra for the amount the arms stick out on the sides.

We are talking about different things here The sunglasses you are looking at are the shades with installed spying gear. Honestly I do not know how good they are and if you can efficiently use them. I guess the ones that would work well would be very expensive. Peter in his post was referring to Spy optic sunglasses. Spy Optic is a brand that makes good sports sunglasses that do not have any additional equipment installed, but feature durable frames and high optical quality lenses.

Going back to the "two-in-one" sunglasses, I know one brand that makes good MP3 Sunglasses. These are sunglasses with a built-in MP3 player. I usually wear them when I am jogging in the morning: my ears enjoy the music and my eyes - sun protection It helps me to wake up better than a cup of strong coffee

Hi Peter Seems like your very familiar with spy [link=http://www.opticsplanet.com/sunglasses.html]sunglasses[/link]. I don't know much about spy [link=http://www.opticsplanet.com/rx-eyeglasses.html]glasses[/link] so I would like to know if this spy sunglasses is worth buying.

It would be awesome if you can give me a list of good spy [link=http://www.opticsplanet.com/rx-eyeglasses.html]glasses[/link]. :)

You will definitely be glad to know what those numbers mean. I always look for them whether I buy online or in a store. (In a store, look for the numbers on the inside of the frame.)

All of the numbers refer to measurements in millimeters.

The first number is the width of a lens. The second is the distance between lenses (width of the nose bridge). And the third is the length of a temple (one of the arms).

A rule of thumb is that sunglasses should be as wide as your face. You can measure your face by holding pencils on each side at eye level and bow down on a piece of paper. To know the width of the glasses, multiply the lens width by two (one for each lens) and then add the distance between lens. Then add around six millimeters extra for the amount the arms stick out on the sides.

The measurements for sunglasses that wrap can be confusing. The width of the lenses is larger and the temples don't have to be as long.

The temple measurement is confusing. The measurement is as if the temple is bent straight out.

It is good if you go to a glasses store and try on a lot of glasses and notice the size of each. It won't take you long to find out which size fits you best.
